Dayco Radiator Coolant Hose P/N:72723
Dayco 72802 lower radiator coolant hose for the 2004-2006 BMW X3 6-cylinder 2.5L or 3.0L carries coolant between the radiator and the engine. This Dayco coolant hose replaces a lower hose that has cracked, softened or started to seep.
Cracks, a soft or swollen hose, or coolant stains at the hose ends can mean it is wearing out. Before you replace it, rule out a loose clamp or a leak at the radiator or water pump, since those can look similar. The car takes one lower hose.
This hose fits the 2004-2006 BMW X3 with the L6-2.5L or L6-3.0L engine.
